In order to prolong the life of the makeup sponge, it is best to wash it after each use. If there is no time, it should be washed at least once a week. Put it in clean water and rub it gently. After picking it up, press it dry with both hands and place it flat in a dry and ventilated place. Do not place it in a damp place, otherwise there will be mold attack; also pay attention to not be exposed to strong light.
